How can you comply with the Energy Efficiency Existing Ship Index (EEXI) and improve the Carbon Intensity Indicator rating (CII) of your vessels without reducing sailing speeds? Here are the top four ways to comply by improving the energy efficiency of your vessels and reducing emissions in the process.
To comply with EEXI regulation and CII, you have two main options. The first is simple: slow down your ship, for example by adopting engine power limitation (EPL) or shaft power limitation (ShaPoLi).
The second option, which this article concentrates on, is to make your vessel more efficient by reducing the amount of energy needed to propel it through the water. Better efficiency means you burn less fuel and reduce your emissions but – crucially – it allows you to maintain market speeds and competitiveness.
The EEXI regulation and CII have been in force since the start of 2023. Both aim to reduce the carbon intensity of international shipping. EEXI defines a minimum energy efficiency level for existing vessels, while CII gives vessels an annual rating on a scale of A to E, with A being the least carbon intensive. Take a look at the Wärtsilä website to learn more about decarbonisation and net zero for the shipping industry.
Four ways to make your vessel more efficient
There are four main ways you can improve energy efficiency and reduce emissions without slowing down your ships:
- Install energy saving technologies
- Install shaft generator systems
- Adopt hybrid systems
- Use alternative fuels
